Preoperative Use of 0.2% Chlorhexidine Digluconate Mouthwash does not affect the Bacteremia following Closed Dental Extraction

Post extraction bacteremia is transitory condition observed in healthy individuals.Aim of the study at hand is to investigate the effect of preoperative rinsing of the mouth with 0.2% chlorhexidine digluconate on post extraction bacteremia following closed tooth extraction. Materials and Methods:This research focused on evidence of bacteremia among 58 individuals, divided equally in two study groupswithout preoperative rinsing (first group) and with preoperative rinsing (second group) with Parodontax Extra (GlaxoSmithKline, Great Britain), followed by open extraction of a single tooth.Aerobic and anaerobic hemocultures (Bact/ALERT, BioMerieux, Inc., Durham, N.C.) were used to establish the bacteremia, while blood samples were obtained preoperatively, 30 seconds after and 15 minutes after the extraction was completed.Results: Preoperative bacteremia was established in 7 (12.07%)patients in total -4 patients from the first and 3 patients from the second group.At the 30 th second after the extraction was done bacteremia was established in 6 (20.69%) patients from the first and in 8 (27.59%) patients from the second group.At the 15 th minute mark bacteremia was found in 3 patients (10.34%) from each group.We failed to identify any statistically significant difference in occurrence of bacteriemia among the subjects in both groups 30 seconds (p=0.548) as well as 15 minutes after the extraction was completed (p>0.05).Conclusions: Rinsing the mouth with 0.2% chlorhexidine digluconate mouthwash does not appear to offer any statistically significant reduction of the occurrence of post extraction bacteremia following typical dental extraction.
